SAE AS23053 | M23053 (AMS DTL23053) Heat Shrinkable Tubing

SAE AS23053 is the active governing standard for military-grade, heat-shrinkable insulation tubing, superseding the legacy MIL-DTL-23053 and MIL-I-23053 designations. To simplify engineering selection and procurement sourcing, the master specification is organized into individual slash sheets (such as AS23053/5 or AS23053/12) based on material formulation, wall thickness, and shrink ratio.

SAE AS23053 heat-shrink tubing serves military, aerospace, and commercial industries. Its diverse slash sheets cover materials like polyolefin, fluoropolymers (PTFE, ETFE, FEP, PVDF), neoprene, Viton, and PVC. These options support operating temperatures ranging from 105°C to 250°C.
